Pressure adjustable type cam clutch mechanism

Abstract

The present invention discloses a pressure adjustable cam clutch mechanism, and comprises a transmission shaft, a self-adaptive automatic transmission mechanism and a pressure regulating mechanism. The self-adaptive automatic transmission mechanism comprises a clutch device and a gear shifting spring; the pressure regulating device comprises a regulating rod and a pressure regulating block; and the regulating rod is rotated to drive the pressure regulating block to axially move to regulate the amount of compression of the gear shifting spring, so as to achieve the purpose of regulating the pretightening force required for automatic transmission. The present invention can regulate the pressure required for the automatic transmission according to the running condition, the running environment and the resistance condition of the vehicle, makes full use of the vehicle driving force, facilitates the optimum matching between the running condition and the driving force output, realizes the gear shifting self-adaptively and automatically along with the changes of the running resistance, and has the advantages of light weight, simple and compact structure, low manufacturing cost, and suitability for the motor-assisted bicycle with small volume and light weight.

Description

technical field [0001] The invention relates to an electric or fuel wheel hub, in particular to a pressure-adjustable cam clutch mechanism. Background technique [0002] In the prior art, electric vehicles, electric motorcycles, electric bicycles and fuel wheel hubs are basically controlled by the speed control handle or the accelerator pedal to directly control the current control speed or control the oil quantity to control the speed, or use a manual mechanical automatic transmission mechanism. Achieve variable speed. The operation of the handle or the accelerator pedal depends entirely on the operation of the driver, which often results in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling. [0003] In order to solve the above problems, a series of automatic transmission hubs have appeared, but the automatic transmission vehicles in the prior art do not have effective adjustment devices, and cannot adjus...

Problems solved by technology

The operation of the handle or accelerator pedal depends entirely on the driver's operation, often resulting in a mismatch between the operation and the driving conditions, resulting in unstable operation of the motor and stalling

[0003] In order to solve the above problems, a series of automatic transmission hubs have appeared, but the automatic transmission vehicles in the prior art do not have effective adjustment devices, and cannot adjust the pressure required for automatic transmission according to the driving conditions and driving environment of the vehicle according to the resistance. , can not be adjusted at any time according to the resistance of the driving environment to adapt to the resistance required by the speed change, can not fully save energy and reflect the advantages of automatic speed change, therefore, it will cause waste of energy

[0004] Therefore, there is a need for an adjustable automatic transmission clutch mechanism, which can adjust the pressure required for automatic transmission according to the driving conditions and driving environment of the vehicle, and the pressure required for automatic transmission according to the resistance situation, and the transmission mechanism can adapt to changes with the driving resistance. Under the condition of driving force, it automatically shifts gears and speeds to solve the problem that the small change of motor torque and speed cannot meet the problem of road use under complex conditions, and the structure is simple, small in size, light in weight, and the space required for mechanism installation is small
